To all whom t may concern.

Be it known that I, @scan C. Porre, a citizen of the United States, residing at Unionville, in the county of Putnam. and Stateof Missouri, have invented certain new and useful Improvements in 'l`railer-'i`rucks; and l do declare the following to be "a full, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyn ing drawings, and to the letters and figures of reference marked thereon, 'which forni a part oi this specification. y My invention relates to. trailer trucks and more particularly to a device of this char acter that is especially adapted t'or the transportation oi pianos or the like, the principal object of ythe invention being to provide a truck upon whicha piano may be quiclriy and easily loaded and safely transported.,

in accomplishing this object l have provided improved details of structure the pre ferr-ed forms of which are illustrated in the accompany Ang drawings, 'wherein Figure l. is a perspective View of a trailer truck embodying my invention, showing a piano mounted thereon and illustrating the manner of connecting the truck with a motor driven vehicle.

Fig. Il is a perspective view of the trailer truck, showing in dotted lines the inanner of loading a piano thereon.

Fig. lll a plan 'view particularly illustrating the body framework of the truck.

Fig. lV is a detail perspective view of the coupling members.

Referring more in detail te the draw ings r- 1 and 2 designate the ground wheels which are of the usual type used in motor vehicie construction fand 3 a connecting axle on which thewheels are suitably mounted.

Supported by the axle 3, through the intermediacy or side springs el, is a body :traine 5 which is preferably oit angle iron construe-- tion and comprises the side `nnenobers 6-7, and rend member 8 and central and forward cross bars 9-10; the side members being efe ,tended forwardly and brought together to form a tongue il whereby the trailer may he drawn.

Mounted-on the trarne `nieinbers dw-i are side boards 13.14, which are oli suihexent height that a piano 'or the nire when meuneupeeiiieatien of Lettera lement;

ed thereon will clear the wheels 1'--2 and not interfere with the travel thereof. i

The slde boards are secured at their lower il also place a cross bar '19, having a i padded upper face, l of the side members, end pro'vide `leather strips 2l along the rear upper edges of the said side members, so that if an uncovered piano should be carried by the truck its sur" face would not be marred should it slip thereon. L Bolted to the side boards 6-7 at the rear upper corners thereof are hooks ft2-22' having points 22B-23" extending above the level. of the said boards and near the forward and rear ends of the sideinenin hers are hooks 24425, which are adapted for receiving the rings 26 of binding strips 27, whereby a piano may be securely ras'H tened on the truck. By placing the hooks 22-22 in this manner, 'when it is desired toload a piano on the truck, the truclr body is tipped from its upright position (d ed lines Fig. Il), so that the hook ends 23-23 may be projected beneath the lower edgeol the piano or the box within which it is contained, and after strapping the piano or box to the truck body7 the same is tipped backwardly to position the same on the truck; the hooks also serving to preventmthe `pianol box from slipping rearwardly from I the truck body.

in order to connect the trailervvith an an tomobile or other conveying vehicle, provide an extended tongue 28 Whlch is secured to the cross members `9410 andI entends fori wardly between the side members 6-7 and to which the same are attached; At the for ward end oi the tongue 28 is an eye inem ber 29 which is adapted for receiving a pin 30, having a ball end 3i for seating between near the forward ends.

upwardly i I also provide a hook 34 near the forward end of the tongue for receiving a tackle hook or the like, to assist in loading as will presently be described, and fenders 35 for covering the wheels 1-2 so that mud or water can not be thrownirom the road against the piano or its covering.

Presuming the device to be so constructed, if it is desired to load a piano thereon, the truck body is tipped baekwardly, so that it 'will stand in an upright position and the hooks 22-22 may be projected beneath the base of the piano. The piano is then strapped to the body by the strips 27 and the truck tipped back to its natural position carrying the piano therewith the tipping may be done manually by drawing forwardly and downwardly onthe tongue or more easily by anchoring one end of a tackle rope to the hook 34 and the other end to the conveying vehicle, so that the truck may be tipped forwardly.

While I have shown a boxed piano strapped to a truck, it is apparent that the piano could be loaded on the truck uncovered andthat the padded bar and side boards will revent `scratching or marring the back of tile pianoe By so constructing the device it will be seen that a piano can uickly and easily be loaded or unloaded and that the truck may be coupled to an automobile and quickly and safely transported.

Havingthus described mv inventionwhat I claim as new therein an desire to secure by Letters-Patent, is

A two 4Wheeled trailer truck comprising a body frame having spaced side members drawn inwardly at their forward ends, cross bars connecting said side members, a forwardly extended tongue secured to said cross members and braced b said inwardly drawn side members, vertical y mounted sideboards secured on the said frame, hooks at the upper rear corners of said side boards, fastening devices on the outer faces of said side boards and an eye member at the forward end of said tongue adapted for receiving a pin on a draft vehicle forth. I

In testimony whereof I ailix my signature.
